Account isn’t my real birthday, need to confirm.

So i made this account a year or so ago, i’m under the age of 18 and for some reason chose to make an adult not student account, something that I don’t know why I did, being an obvious violation of tos. But having just started using it again I put about $200 into the account, bought some clothing, before my account got locked with me needing to prove details. Everything is legit except my birthday, and all transactions are legitimate. Not sure what my course of action should be? If you could help me out i’d be grateful.
